The moment the 6-foot-2, 178-pound pro obstacle racer steps into a competition, he is sizing up his opponents, picking apart their weaknesses and planning his attack. That mentality was what McIntyre believes set him apart in Season 4 of “Steve Austin’s Broken Skull Challenge,” in which the 27-year-old emerged victorious among eight of the top dogs from previous seasons. The show premiered Sunday, Jan. 22, on CMT.
